The new version of the Oak Segment Tar present in AEM 6.3 requires a repository migration. This step is mandatory if you are upgrading from an older version of TarMK or want to switch the new Segment Tar from another type of persistence. For more information on what the benefits of the new Segment Tar are, see the Migrating to Oak Segment Tar FAQ.

User Interface

The Classic UI is included in AEM 6.3. Mind that most entry points from within the Touch-optimized UI, that were enabled by default in version 5.6-6.2, to switch to the Classic UI equivalent have been disabled by default.

Atenție:

Adobe is planning to deprecate the Classic UI in AEM in April 2018. The 2018 release of AEM will still contain the Classic UI as it is part of current AEM release. Following that, Adobe is planning to remove the Classic UI from AEM in April 2019. Read more.
